EYEGLASS CONNECTION.

Specification of Letters Patent.

Patented Feb. 12, 1907.

Application filed August 14, 1906. Serial No. 330,602,

To ttZZ w/tmn it vita/ concern/.-

Be it known that I, SAMUEL N. STONE, citizen of the United States, residing at Attlebore, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Eyeglass Connections, of which the following is a specification.

My invention relates to eyeglass connections, and has for its object the improvement of the eyeglass connection shown and described in my application for Letters Patent of the United States filed February 15, 1906, Serial No. 801,197, in regard to certain features of construction hereinafter set forth.

An essential feature of my said application and a part of equal importance in this application is that which is termed the box, and the differences in construction constituting my presentinventicn are set forth below and in the accompanying drawings, of which Figure 1 represents, much enlarged, a por tion of a pair of eyeglasses with the eyeglass connection constructed in accordance with my invention, the box being shown in vertical section. Fig. 2 is a cross-section of the post on line X X of Fig. 1 and shows a bottom view of the box upon the end of the post. Fig. 3 is a top view of the box. Fig. 4 shows a portion of an eyeglass-lens and a horizontal section of the eyeglass connection embodying my invention.

Like letters are used to refer to the same parts throughout.

In the drawings, the letter A designates the lens, and the letter B the lens-clamp, provided with the interiorly-threaded sleeve b.

The crescent-shaped edge brace is marked C, and the recess therein is designated by the letter 0.

Letter D refers to the post, the lugs or wedge-shaped sides of which are marked at, and the central cylindrical passage in the post is designated d.

The bow-spring is marked E.

The nose-guard is referred to by the letter F and has the arm The box is referred to by the letter G. It comprises the flat top g, provided with a screw-hole. Integrally formed with the top are two opposite continuous side walls 9 and two opposite side walls 9 pierced by corresponding openings 9 The bottom of the box is open, and it is constructed with a beveled edge 9 In assembling the parts the clamp B engages the lens in the usual way. The sleeve 1) of the clamp is fitted into the passage d of the post, and the bends l) at the tops of the legs of the clamp engage the recess 0 of the crescent C, which prevents the turning of the clamp with respect to the crescent post. In the usual manner I construct the crescent and post together of one piece ofmetal. The box G is placed over the end of the post, and the bow-spring and end of arm f of "the nose-guard are inserted one upon the other through openings 9 in the side walls of the box. Screw H being passed through the top of box G and through suitable holes in the spring and arm of the guard engages the threads of the sleeve 1) of clamp B and secures the various parts of the connection together. The screw being set up tightly, as a further fastening expedient the beveled edge g of the bottom of the box is turned in under the head of post D, as shown in Figs. 1, 2, and 4. Thereafter the post and box remain together, and even should the connection be taken apart the box with the post and its crescent base are handled as one piece. The box may always be readily removed, however, with the tweezers.

In my present invention I retain all the advantages of the box element, comprising great strength for the weight of metal, and the construction preventing the continuous side walls g from separating, thus doing away with the necessity for using solder. By turning in the edge 9 of the box the effectiveness and security of the fastening is materially in creased.

Having now described my invention and explained the mode of its operation, what I claim is 1. In an eyeglass connection, the combination with a post having a head, of a box having a closed top and two opposite continuous side walls and two opposite side walls having corresponding openings, the bottom of said box being open, the said box being arranged to inclose the head of the post and the bottom edges of the box being turned inwardly beneath said head, a bow-spring and a noseguard having ends passed one on the other through the openings in the said walls of the box, and a screw passing through the top of the box and through said bow-spring and nose-guard and into the post whereby the parts are clamped together, substantially as described.

2. In an eyeglass connection, the combination with a post having a head having lugs provided with exterior inclined surfaces, of a box having a closed top and two opposite continuous side walls having interior inclined surfaces and two opposite side walls having corresponding openings, the bottom of said box being open, the said box being arranged to inclose the head of the post and the bottom edges of the box being turned inwardly beneath said head, a bow-spring and a noseguard having ends passed one on the other through the openings in the side walls of the box, and a screwpassing through the top of the box and through said bow-spring and nose-guard and into the post whereby the parts are clamped together, the inclined surfaces of the box engaging the inclines of said lugs and pressing the lugs inwardly against the nose-guard and bow-spring, substantially as described.

3. In an eyeglass connection, the combination with a lens-clamp having a threaded sleeve, of a crescent or edge brace and hollow post, the said crescent having a transverse recess at the base of the post, the said clamp engaging said recess and the sleeve of the clamp being inserted into the hollow of the post, the said post having a head, a box having a closed top and two opposite continuous side walls and two opposite side walls having corresponding openings, the bottom of said box being open, the said box being arranged to inclo'se the head of the post and the bottom edges of the box being turned inwardly 1 beneath said head, a bow-spring and a noseguard having ends passed one on the other through the openings in the side walls of the box, and a screw passing through the top of the box and through said bow-spring and nose-guard and into the sleeve of said clamp whereby the parts are clamped together, substantially as described.

4. In an eyeglass connection, the combination with a lens-clamp having a threaded sleeve, of a crescent or edge brace and hollow post, the said crescent having a transverse recess at the base of the post, the said clamp engaging said recess and the sleeve of the clamp being inserted into the hollow of the post, the said post having a head, a box having a closed top and two opposite continuous side walls having interior inclined surfaces and two opposite side walls having corresponding openings, the bottom of said box being open, the said box being arranged to inclose the head of the post and the bottom edges of the box being turned inwardly beneath said head, a bow-spring and a noseguard having ends passed one on the other through the openings in the side walls of the box, and a screw passing through the top of the box and through said bow-spring and nose-guard and into the sleeve of said clamp whereby the parts are clamped together, the inclined surfaces of the box engaging tlie inclines of said lugs and pressing the lugs inwardly against the nose-guard and bowspring, substantially as described.

In testimony whereof I aiiix my signature in presence of two witnesses.
